<P>If a number of circular through hole pads (Pads,paste mask) on a equal distance needs to be included, this function can do the job. In the next dialogbox all the necessary parameters can be entered. After pressing the <B>OK</B> button the pads can be placed. When pressing the <B>right mouse button</B> the pads will rotate 90 degrees counter clock wise. By pressing and keep down the <B>shift</B> key and moving the mouse cursor, the moving center will change. When the <B>spacebar</B> is pressed, a dialogbox will popup, and the position of the first pin can be edited by hand. When the first character typed is a <B>@</B> the coordinates will be relative against the <B>Relative (grid)position</B>. The coordinates typed in will be used with the current units (dimension).</P>

<P>The function <B>Add SIL based on selected objects</B> will do the same, but the dialogbox parameters will already be filled, with the parameters of a <B>selected</B> pad.</P>

<P>The following parameters can be changed:</P>

<P><U>Pad size</U></P>

<P><U>Pitch</U></P>

<P><U>Nr pins</U></P>

<P><U>Pad size solder mask</U></P>

<P>If the solder mask pad is not necessary, fill the parameter with zero.</P>

<P><U>Diameter anti power pad</U></P>

<P>The anti power pad will always be a circle.</P>

<P>If the anti power pad is not necessary, fill the parameter with zero.</P>

<P><U>Diameter inner pad</U></P>

<P>The inner pad will always be a circle.</P>

<P>If the inner pad is not necessary, fill the parameter with zero.</P>

<P><U>Drill hole</U></P>

<P><U>Clearance</U></P>

<P>The initial clearance is the clearance used for this geometry.</P>

<P><U>Pintype</U></P>

<P>The pin can be a square or a circle.</P>

<P><U>Startpin</U></P>

<P>The startpin consists of two editboxes. The first editbox(optional) contains text or a number, and will not be changed. The second editbox contains a start number. This startnumber will be increased with <B>Increment</B> for the next pads.</P>

<P>The <B>Use default rules for solder paste/mask, inner/anti power pad and clearance</B> button can be used the fill in values based on the drill size.</P>
